Cell Cycle and Cell division Flashcards
Limits to Cell Growth
larger the cell becomes the more it demands a cell places on its DNA, and it has trouble moving all material across the cell membrane
Cancer
Cancer occurs when cells of your body begin to divide uncontrollably and form a tumor, uncontrolled cell growth
Cell Cycle
During the cell cycle cells grow, prepare for division, and divide into two daughter cells
interphase
The cell spends most of its time here.
Cell grows, chromosomes are replicated, Organelles required for cell division are produced.
Mitosis
Cell division
Has 4 phases
The process by which a single parent cell divides to make two new daughter cells, identical, replace, repair, grow organism - all cells but sex cells
Prophase
the first stage of cell division, the process that separates the duplicated genetic material, chromosomes condense
Metaphase
the second stage of cell division, the chromosomes become attached to the spindle fibers, they line up in the middle, it leaves the cell
Anaphase
the chromosomes move away from one another to opposite poles of the spindle, they are being pulled apart
Telophase
chromosomes move to opposite ends of the cell and two nuclei are formed
Cytokinesis
the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.
